VoLz, a citizen of the United States, residing in Mil-' waukee,; in the county of Milwaukee and Wisconsin, have invented new and useful Im rovements in Apparatus for Pas- Be it knownt at I, SIMON 'teurizing ottled Liquids, of which the followingis a description, reference being had a part of this specification.

Myinvention has relation to an improved for pasteurizing bottled liquids. The primary object of the invention is to provide an improved apparatus, whereby the water or the pasteurizing agent in which the bottles are sterilized is gradually heated to a uniform heat thehighest temperature of. the pasteurizing agent being maintained at a point intermediate of the initial and final contact of the liquid containing recepger of breaking the bottles, and alsti preventing the beer, or other liquids, from having a burnt or disagreeable taste, or being otherwise delete riously afl'eeted,'-whieh is the casein processes and apparatuses where-c in this fgradual heating is not present, the

pasteuriz ng in the case of my invention being carried out in a minimum of time, .and

in. a manner to secure the most effective pastenrizing results.

j fur her object contemplated by my inventio'n,is"the?-provision of an apparatus for motin the receptacles containing the liquid intermittently through the pasteurizing agent ,fto accomplish the improved results here nafter set forth.

Application filed August 6, 1808. Serial No..4=4,7,226.

1 Fig.' 7 is a cross section on the line 7-7 of Fig. 5 looking toward the left with part broken away.

Referring to the drawings, the numeral 8,

indicates a pasteurizing tank. This tank is closed throughout, excepting that its top is provided near. the forward end thereof and parallel with and adjacent to its lateral edges, with elongated openings 9, 9, said openings being of sufficient width to admit of the passage'therethrough of the bottle carriers hereinafter referred to.

Near opposite ends of the tank are located interior transverse partitions 10, 10,

said partitions extending from the bottom partitions are of such length that their ends join the transverse partitions ,10, 10. The said longitudinal partitions divide .the tank into three compartments, designated, respectively, by the numerals 14, 15 and 16.

Connected to the opposite sides 'of the tank and extending a desired distance above the top of said tank are a series of beams 17 which, for the purpose of strength, are pref-v erably U-shaped in cross section.

These beams notonly serve to brace the sides of the tank and prevent the bulging out thereof, but also serve as a sup ort nism located above the tank. Each set of opposite beams 17 sup ort at their upper ed beams 18. The two rear transverse beams 18 are connected 3y three longitudinal beams 19, 19f and 19". ournaled in'suitable hearings in the said for mechas three beams is a transverse driving'shaft 20.

This shaft carries thereon'loose and 'fast pill-- leys 21 and 22 respectively, around which a belt (not shown) leading from any suitable, 1 v

23 which is adapted to source of power, is adapted to pass. Fast on mounted on a second transverse shaft. 25,

said secondtransverse; shaft being) mounted 1n bearings inx the longitudinal eams 19' and 19", Shaft 25 has fast thereon a pinion 26 which meshes witha large toothed wheel "27 mounted on a short transverse shaft '28,

which latter shaft is also mounted in bearings .on the longitudinal beams 19 19". Shaft-28 carries a mutilated gear 29, which is adapted to intermittently engage a worm gear 30 carried at the upper end of a vertical shaft 31, the lower end of said vertical shaft being mounted in a bearing formed on the top of the tank, and also in a bearing carried by the transverse beam 18 at the rear end of the machine. Just above its. lower end the shaft 31 carries a sprocket Wheel 32. There is also at the rear end of the machine another vertical shaft 33 which carries a sprocket wheel 34, said shaft having a bearing at its lower end in thetop of the tank, and a bearing at its upper end in the rear transverse beam 18. more, two corresponding vertical shafts designated, respectively, by the numerals 35 and 36 at the forward portion of the machine, the lower ends of said shafts likewisev having their hearings in the top of the tank, and their upper ends in the forward transverse beam 18. These shafts carry respectively sprocket wheels 37 and 38.

Supported below the transverse beams 18 is a serpentine trackway. The support for this trackway may be of any desired form, but. I prefer to provide the particular construction shown in the drawings, a description of which will now be given. Secured to and depending from each of the several transverse beams 18, are hangers or arms'39, These arms are arranged 1n pairs, the'two arms of each pair being-parallel and equidistant apart. 1

Each of the transverse beams, with the exception of the extreme forward beam, has eight of these hangers depending therefrom, while the extreme'forward transverse beam has'only four of said hangers depending therefrom. Fig. 3 shoWs the eight depending hangers, and Fig. 4 the four depending hangers relating to the extreme forward transverse beam. In the case of the depending hangers, with the exception of those depending from the forward transverse beam, the lower ends of said hangers, excluding the extreme outer hangers, are connected by horizontal connecting arms 40 which extend laterally beyond the ends of the respective vertical hangers which they connect, and thereby not only serve to prevent spreading apart of the hangers, but also form lateral outstanding feet for the support of the rails forming the trackway. The extreme outer hangers of the transverse beams 18 just referred toare free from connection with the horizontal arms 40. Their lower ends, however, are bent inwardly at right angles (as most clearly shown in Fig. 3) to form supports for the rails connected thereto. In the case of the four hangers 39 depending from the forward transverse beam 18, the

lower ends of the hangers of each pair are There are, further- 'bent inwardly toward each other-to form supporting feet for the rails. The track is composed of rails 41, preferably of angle iron form. These rails are supported by the inwardly turned feet at the lower ends of the depending hangers of the forward transverse beam 18 ,(see F ig. 4)

and by the projecting ends of the horizontal It will be noticed that the. upwardlyex- 1 tending beams 17 at the forward end of the machine extend upwardly a greater distance than any of. the succeeding beams. This necessarily increases the'height of. the forward transverse beam 18, and consequently the trackway suspended by the hangers 39 of said forward transverse beam is on a higher plane at this point, being in fact on.

a level for a short distance rearwardly. From the rear terminus of the level portion, the track is on a decline until such 'lower point is reached as will permit of the rails being supported by the hangers 39 depending from the transverse beams l8 which are carried at the upper ends of the'shortverti-- cal beams 17.

Following the course of the serpentine I trackway from its level forward point, such track-Way des'cendsto a point Where it is supported by the hangers depending from the transverse beams" supported at the upper ends of the short vertical beams 17, as justexplained. It then continues on a horizontal plane-.along one side, thence circles around the rear sprocket wheel 34, thence continues from the rear forwardly ina horizontal plane, thence makes a tu'rn just .to the rear of the forward transverse beam 18,

thence continues from this turn rearwardly. in a horizontal plane and circles around the sprocket wheel 32, thence continues forwardly along the opposite side and one horizontal plane for a distance somewhat greater than one-half the length of this side of the machine, thence upwardly at an incline' eorre'sponding to the initial inclination already referred to, thence around on a horizontal plane to the starting point.

A sprocket chain 42 is driven by the sprocket wheel 32 carried on the vertical shaft 31. Following the course of this chain after it leaves the sprocket wheel 32, it extends forwardly in one medi' 1 length to and around a sprocket Wheel 4 carried on a short stud or spindle 44, thencerearwardly in a second medial length to and around the other rear sprocket wheel 34, thence forwardly and around the forward sprocket wheel 38, thence along the forward end of the machine in a transverse direc-' tion and around the other forward sprocket wheel 37, thence along the other side and .belowthesprocket c ain 42, 7

between the fur'c'ate members of the bifur-v longitudinally to join. the initial starting point of the chain,.i. 6., at the rear sprocket wheel 32. I

It is desirable that means be employed for tightening the. sprocket chain, and for this purpose I mount the spindle 4-1 of the sprocketwheel 43 in a box 45 which box is slidable in guide'ways 46, 46. The box is moved forwardly or rearwardly by means of a screw 47, revolubly. connected at its forward end to the box and passing through a threaded opening'in an upwardly extending bearing 'lug 48. The rear end of the screw is advisably provided with a hand wheel, for convenience in turning the same. It is obvious that when the screwis, turned in one direction, 'it will move the. bearing box 45 forwardly and thereby tighten the chain, and consequently take up slack. r

-The frames which support the bottle crates each consist of a U-shaped structure 49, the depending arms thereof at their lower ends being bent inwardly to form feet to which is riveted a plate 50 In order to prevent the plate from tilting sidewise, diagonal arms 51, 51 extend from the depending arms of the frame and these diagonal arms arefllikewise formed at their lower ends. wlt'h mwardly extending feet to which the plate 50 is riveted. .The frames 49: are adapted to support a rectangular bottle crate 52, and' each plate 50' forms the bottom ofeach crate, the bottles 53 resting on said bottoms and being supported thereby.

Each carriage consists of an axle 54cupon which are mounted .wheels 55, 55, said wheels adapted to'ride on the rails 41. Depending centrally from each axle 54 is an arm 56. Each of these arms is connected to the sprocket chain 42, and therefore' forms a 1 part ofsaid chain, each arm being formed with an opening 57 into which the teeth-o the several sprocket wheels are adapted to engage, the said opening being in alinement with the elongated openings of the links of the 'sprocketohain (as most clearly shown in Fig 4t)?- The a s 56 extend slightly 'and are pivoted c'ated end'of an arm '58 extending upwardly from the fcenteii ofieach U-shaped frame 49, said arm.58 being preferably; integral withthe said frame. 1 It will be understood that the frames 49 and the bottle crates carried thereby are within the tfinkS, and hatthe upwardly. extending arms 58 are 'ad ,pted to Pam through and travel in aserpentine slot ;.;mem"frem the forward level plane down! the incline would haves-tendency at ,the'

, lower end of, said incline. to-jun'up.upwardly'.=x .The same "wouldalso be itruefinregard to. f the final movement of the machine on the" to guard opposite side, where the chain moves upwardly at an incline. To guard against this tendency short auxiliary inverted U-shaped rails 60 are employed on opposite sides of the machine. at the terminus of the decline. The Wheels 55 of the carriers are adapted to pass beneath these rails, and consequently I said rails prevent any up movement of the carriers, as just referred to.

Extending transversely of the forward portion of the tank, in advance of the partition' 10, is a shaft 61, said shaft having a series of blades 62 radiatingtherefrom. This shaft and its blades form .a circulat-v ing pump. One end of shaft 61 is extended through one side 'of-the tank, and. carries thereon a belt pulley 63, said belt pulleyconnected up to another pulley 64 on the outer end of the driving shaft 20 by means of an endless belt 65. It is obvious that when the drive shaft 20 is rotated rotation is conveyed to shaft 61 through the medium of the belt and pulleys just referred to.

Above that side of the tank from which pipe 67 enter- 20. Through this medium the rotation of d the drive shaft 20 is conveyed to the fan shaft.

Short longitudinal partitions 71' and 72 are disposed within the central compartment 15. of the tank. Partition 71 extends inwardly from the rear transverse partition 10 for a desired distance, and partition-72 starts at a point just to the rear; ofsprocket wheel 43 and rearwardly fora desired dis,-

tance. The inner ends of the two partitions 71 and 72, however, "do notmeet but are a considerable distance apart. Within that portion of the tank between the "rear partition 71 andftheright hand partition 13 (Fig. 3) is a siphon injector, consisting of a tube 73 arranged at the bottom of the tank and extending from a point just in advance of the rear partition inwardly for a desired distance, and a steam pipe 74' leading from any suitable source of steam supply and extending'throughthe top ofthe v tank and downwardly and thence bent hori-f" zontally and extended into therear end of the tube 78 fora short distance.

In--tl1e useo'f'the apparatua-the of steam supply to" the pipe 74 --is 'turned" on; The steam issues out of the lolwer'endf of -said pipe into the tube] l3,'a'nd tlrience- .-passes iiito" the pentralcompartment 15?" the-tank, This siphon injector, therefore is the means provided for keeping ele a e inthe 'tank'in a he ted condition, "a dthis injector discharges into .the central coinpartment- 15, the water in this compartment is naturally maintained at a higher temperature than in' the other compartments of the tank.

The bottles containing the beer, or other liquid, are corked as usual and placed on the bottom ofthe crates 52. The crates so filled with the bottles to be sterilized are now placed in the cages or frames 49 which are at the forward level portion of the apinto the compartment 14 of the tank. The

perpendicular position of the cage and its crate is maintained during the descent of the carrier down the incline by reason of the pivotal connection between the. arms 56 and 58, as clearly shown in Fig. 1. It'will be evident that the movement of the advancing carrier, as .Well .as all succeeding carriers, is

intermittent, by reason of the provision of the mutllated' gear 29 which only engages the worm gearduring a portion of its rotation. Each cage and its bottle crate, therefore, are first lowered intothe compartment -1 14 of the tank, and' at the terminus of the decline continues its travel along said compartment 14 rearwardly and on a level when they first enter the water in the compartment 14 of the tank have the effect of i cooling the water in said compartment.

When the bottles reach the central compartment 15 they encounter the hottest water, and hence during their travel back and forth in this compartment are thoroughly sterilized. ,The bottles on reaching the terminal compartment 16 encounter the cooler body of water, inasmuch as the water in thiscompartment is cooled by the action of the fan 66. In addition to the water in compartment 16 being cooled by the fan 66 it is also cooled by the action of the circulating pump 61'62, which pump serves to suck the cooled water 'in the initial compartment 14 out of said compartment through the opening 11 into the forward portionfof the tank in advance of the forward transverse partition 10, thenie through the other opening 11 and into the 'erminal compartment 16. The fan of course causes a circulation of air around the tank, and this air becomes gradually warm by absorbing heat units from the warm.water. This warm air comingin contact with the bottles as they enter the initial compartment 14, serves to assist in warming minal compartment 16 is'not onl cooled by the action of the fan, but also y the coolwater sucked around-by the pump. It is im- 'portant that this cool water should be preplane. Each cage and, crate with the bot y vented from passing into thecentral comtles is carried to the extreme rear end of th compartment 14, and then around the rear end of partition 13, entering .the central compartment .15. In this compartment the cage and its crate travel forwardly, circling around the shaft 44, and thence travelrearwardly to the rear end of the compartment 15, and backwardand forward travel in said compartment .15 also beingon a level'plane. The cage andits crate next pass around the rear end of th'e other partition 13, and thence forwardly in compartment 16 on a level plane until the carrier reaches the inclined portion of the trackway. In traveling up this inclined portion of the trackway, the

cage-and crate are lifted upwardly and through the opening 9 out of the tank, finally traveling to the starting point, or the forward level portion of the apparatus, at which point the crate containing the pasteurized bottles is removed from itscage and another crate containing bottles to be pasteurized substituted therefor.

* The bottles when first placed in their crates are in a cool condition, and hence temperature.

is of course maintained by the pump,'and the cooled water which has been drawn from the initial compartment 14 into the terminal partment 15 and thereby cooling the water in said compartment, and which water it is .a desideratum to maintain at the highest The circulation of the water compartment :16 is drawn from said latter compartment through an opening 75 between one endbf the rear partition 10 and, the side of the,tank, thence across the rear transverse space 76, thencethroughanopening 77 between the opposite end of the rear transverse partition 10 and the side of the tank, and thence into the initial compart-' .fiected out of the compartment 15, and

through the opening 75.

chine. In some instances, it may be desir a able to use the machine as a leftv hand ma-.

chine. In that event, all that is necessary visto transfer the air fan from the compart ment 16 to the compartment 14, and run the circulating pumpinr ad'irection opposite to that in which it is run as ,a right hand machine. The bottles or receptacles under this arrangement first pass 'into the compartment 16 instead oft'he compartment 14. Another advantage possessed by my invention to which I have not heretofore called attention is the fact that thcchain carry- "ing the carriages is out of the water during the entire travel of the carriages. In .devices wherein the chains are submerged in the water, the said chains deteriorate quite rapidly, the period of time during-which they can be 'used" being, only about six:
